Deeper analysis
The Startklar Elementor Addons plugin for WordPress contains an arbitrary file upload vulnerability in versions up to and including 1.7.13. The flaw stems from missing file type validation inside the process function of the startklarDropZoneUploadProcess class, allowing files to be written to the server without restriction. The issue is tracked as CWE-434 and carries a CVSS 3.1 score of 9.8.
Unauthenticated attackers with network access can send crafted requests to the affected upload endpoint and place arbitrary files, including web shells, on the target server. Successful exploitation can lead directly to remote code execution with the privileges of the web server process, without requiring authentication or user interaction.
A fix was published in plugin changeset 3081987 on the WordPress Trac repository, and Wordfence has published a corresponding advisory detailing the affected code path. The current EPSS score of 0.1496 has not shown material increase since disclosure.

Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.
Requiring identifiable owners for portable devices reduces the attack surface for unrestricted uploads of dangerous file types via anonymous media.
Dangerous file uploads can be detonated in the chamber to determine malice before any production write or execution occurs.
Prevents unrestricted writing of arbitrary or malicious firmware by keeping hardware write-protect enabled except under tightly controlled manual procedures.
Scans files from external sources on download/open/execute, blocking unrestricted uploads of dangerous file types.
